This design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking rotors that maintain performance under demanding conditions while fitting specific Mercedes-Benz SL models.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is a solid type, measuring 278mm in outside diameter and 58.3mm in overall height. It features a plain disc finish with a zinc silver hat finish that resists rust. The rotor includes five bolt holes with a 112mm bolt circle diameter and a center hole diameter of 67mm, ensuring proper alignment and fitment. The surface is directional with both drilled holes and slots, designed to improve braking efficiency and reduce heat buildup. The nominal thickness is 9mm, with a discard thickness of 7.3mm, indicating when the rotor should be replaced to maintain safety and performance.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped brake discs on Mercedes-Benz 300SL, 500SL, SL320, and SL500\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive or prolonged braking\u003c\/li\u003e\n\u003cli\u003eHelps maintain consistent braking performance under high-stress conditions\u003c\/li\u003e\n\u003cli\u003eAddresses corrosion issues with rust-resistant coating for longer rotor life\u003c\/li\u003e\n\u003cli\u003eRestores proper braking surface for enhanced safety and control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 7.3mm before installation. Clean the hub surface and mounting points to prevent uneven rotor seating. Use the correct torque specifications for the 5 bolt holes with a 112mm bolt circle diameter. Since this rotor is directional, verify the rotation direction matches the vehicle’s wheel rotation for optimal performance. No additional hardware is included, so use existing or manufacturer-recommended components during installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-63018L rotor to meet OEM specifications for Mercedes-Benz SL models.
